VANCOUVER — A concept for a proposed third bridge over the Columbia River in Clark County has been revealed.

The Vancouver Columbian reports the proposed bridge, championed by Clark County Commissioner David Madore, would cross the Columbia River from Highway 14 at Southeast 192nd Avenue in Vancouver, jog to the west slightly, cross Government Island and connect to Northeast Airport Way in Oregon. The bridge would feature four lanes for motor vehicles and two covered lanes for bike and foot traffic.

A third bridge has long been considered as an option to relieve congestion between the two states. Madore has been an opponent of revamping the Interstate 5 river crossing, a two-state plan that is moribund after Washington lawmakers balked at authorizing money. That bridge plan includes light rail and cost an estimated $2.9 billion but would include federal money.

At an estimated $860 million, Madore says a third bridge is a common sense approach to relieving congestion.
